    Abstract: Das Polarisations-Fourier-Transform-Spektrometer weist zur Erzeugung eines Wegunterschiedes zwischen zwei Teilstrahlen unterschiedlicher Polarisation mindestens eine doppelbrechende planparallele Platte (5) auf, welche dreh- oder kippbar gelagert ist. Durch die Drehung oder Kippung der planparallele Platte (5) wird eine Änderung des Einfallswinkels α erzeugt, so dass der genannte Wegunterschied hervorgerufen wird. Als Absorptionsspektrometer weist das Spektrometer einen polychromatischen Lichterzeuger (1), einen Kollimator (2a), eine Probe (3) und einen Polarisator (4a) auf. Während der Veränderung des Wegunterschiedes wird von einem Detektor (7) die Intensität von Licht (L) gemessen, das die mindestens eine planparallele Platte (5) und einen Analysator (4b) durchlaufen hat. Aus dem so entstehenden Interferogramm wird in einer Signalverarbeitung (8) mittels FourierTransformation das Spektrum der Probe (3) bestimmt. Das Spektrometer ist einfach und robust, und es werden zeitaufgelöste Messungen ermöglicht.

    Abstract: A method and apparatus for spectral imaging system is provided. The system is for measuring the fluorescence, luminescence, or absorption at selected locations on a sample. An interferometric spectral discriminator creates an interferogram. The system can be calibrated with a slit (503). A large offset in the pathlength in the interferometer can be introduced to produce a high fringe density thus creating a monochrome image. A metaphase finder is used to locate areas of interest.

    Abstract: The present invention provides a scanning apparatus to obtain automated, rapid and sensitive scanning of substrate fluorescence, optical density or phosphorescence. The scanner uses a constant path length optical train, which enables the combination of a moving beam for high speed scanning with phase-sensitive detection for noise reduction. The constant path length optical train comprises a light source, a scanning mirror (40) to receive light from the light source and sweep it across a steering mirror (50), the steering mirror receives the light from the scanning mirror and reflect the light to a substrate wherein the substrate reflects the light to a photodetector (70).

    Abstract: This invention provides a method of determining a trace gas concentration in a gas sample utilising Fourier Transform Infra-Red Spectroscopy, said method comprising the following steps i) to iii) of: i) synthetically calibrating a spectrometer by the steps of: a) calculating a theoretical spectral response function for a series of candidate chemical substances; b) convolving said theoretical spectral response function with a spectrometer instrument response function corresponding to said spectrometer device so as to produce an expected response function for said series of candidate chemical substances; and c) utilising said expected response function as the calibration of said spectrometer device in the subsequent measurement of chemical substances; ii) determining a spectral window within which to fit a calculated spectral trace to an experimental spectral trace by the steps of: a) choosing a series of candidate windows; b) determining the likely error measure associated with a fitting of said spectral trace for each of said series of candidate window; c) utilising said likely error measure associated with each of said fitting to determine a final window having substantially the lowest likely error measure; and d) utilising said final window as said spectral window; and iii) utilising said calibration and said spectral window to fit a calculated spectral trace to a spectral trace measured by the spectrometer and to thereby determine the concentrations of constituent gases and/or the ratio of the concentration of one isotope isomer (i.e. isotopomer) to that of another isotopomer of the same molecular species.

    Abstract: Standardization is achieved for FTIR spectrometric instruments that effect an intrinsic distortion in spectral information, the distortion being associated with an aperture size. An idealized function of spectral line shape is specified. With a small calibration aperture, spectral data is obtained for a basic sample having known "true" spectral data, and standard spectral data also is obtained for a standard sample. With a larger, normal sized aperture, standard spectral data is obtained again for the calibration sample. A transformation factor, that is a function of this data and the standardized function, is applied to spectral data for test samples to effect standardized information. In another embodiment, the standard sample has known true spectral data, and the basic sample is omitted. In either case, the transformation factor is applied to the sample data in logarithm form, the antilogarithm of the result effects the standardized information.

    Abstract: An optical interferometer 1A includes a branching-combining unit 10, a first optical system 20, a second optical system 30, and a drive unit 40, which can be MEMS-based components. The branching-combining unit 10 includes a branching surface 11, an incident surface 12, an output surface 13, and a combining surface 14 on an interface between the interior and the exterior of a transparent member. The branching-combining unit 10, on the branching surface 11, partially reflects incident light L 0 and outputs as first branched light L 11 , and transmits the rest of the incident light into the interior as second branched light L 21 . The branching-combining unit 10, on the combining surface 14, outputs the first branched light L 12 to the outside, reflects the second branched light L 22 , and combines the light beams to be output to the outside as combined light L 3 . Thus, a MEMS-based optical interferometer capable of decreasing light loss from branching to combining and improving interference efficiency is realized.
